"Open Mercato Hackathon. How we built an AI-powered service system in 1,5 days You don't always need to master a technology before you start using it. Skeptical? The HackOn Open Mercato hackathon proved otherwise." commerceweavers.com/blog/open-merc…

Open Mercato is an open-source CRM/ERP framework built on Next.js App Router + TypeScript. MIT license. Multi-tenant. No vendor lock-in. We just crossed 100 contributors in the project 🚀 We’re building in public. github.com/open-mercato/o… @nextjs @TypeScriptLang @eddiejaoude

@tomik99 LFG!

Do you know the biggest production ready code base 100% written with AI? Check @OpenMercato, 800k lines and growing with over 100 contributors, none of them wrote a single line of code.

Self-driving companies won't run on prompts alone. They need systems that run work. @MulticaAI agents on @OpenMercato: - open-source, programmable CRM/ERP core - built-in permissions, workflows, APIs - human handoff when needed Building blocks for self-driving orgs.

OG team leaving Sopot. Damn, three days locked in hacking with @OpenMercato team or should I say - chatting with Codex 🤡 First time we got to enjoy the city! Shipping some cool stuff later next week! 🥵

I just spent an afternoon with the CTO of a large European Company. 20 years of software legacy, eight-figure licensing bill, 500+ engineers. The 6 questions every enterprise CTO asks about AI engineering x.com/tomik99/status…

Super excited to be at the @OpenMercato Hackathon in Sopot! 🚀 2nd hackathon in a month — fully in the zone. Can’t wait to see what we build!

Full house at @OpenMercato Hackathon!

The Open Source math that many companies still don’t understand. We’re building something that would cost millions to recreate from scratch. And… we give it away for free. Then someone asks: “Why does consulting for this cost $150/hour?” Here’s the thing: Open source isn’t cheap. It’s already been paid for. Thousands of hours. Dozens of senior engineer months. Real IP that normally sits behind paywalls or inside closed systems. With Open Mercato, we put it all on the table. Code. Architecture. Thinking. AI has broken the economics of software. Projects that used to be impossible to justify suddenly make sense. 2–3x faster development. Estimates that used to scare clients start closing. But here’s where people get it wrong: You’re not paying for code. You already have the code. You’re paying for decisions. Decisions that cut months off your project. Decisions that help you avoid mistakes that cost a fortune. Decisions from people who built the system and know exactly where the landmines are. That’s why it’s $150/hour. Because this is the rarest resource on the market. You pay for a few hours of an expert and get access to IP worth millions. You compress time-to-market. You skip the mistakes that kill projects. This is knowledge arbitrage. Open source isn’t charity. It’s a business model. It accelerates adoption. Lowers the barrier to entry. And monetizes what’s truly scarce: Context. Experience. Judgment. Everything is open. You can take the code and build it yourself. Or you can move faster with our consulting partners. Your call.

It was a blast! Great conference, awesome talks and @OpenMercato fast intro in 15 minutes.

@OpenAI Codex will support our Agentic Software Engineering Open Mercato Hackathon! All participants will receive a set of tokens and a “Codex Tool Intro” session by @grabbou! Huge thanks! Let’s build something amazing together!
